Gravitational Collapse in the EGB Gravity
Ayan Chatterjee, Avirup Ghosh, Suresh Jaryal
The Einstein- Gauss- Bonnet (EGB) gravity is an important modification of the Einstein theory of gravity and, for many gravitational phenomena, the Gauss- Bonnet (GB) correction te…
Inducing supertranslations: The membrane picture
Avirup Ghosh
Dynamical evolution of black holes may be studied perturbatively in the membrane picture. We study the case of a body freely falling into a black hole, in the Rindler approximation…
Decaying fermionic warm dark matter and XENON1T electronic recoil excess
Koushik Dutta, Avirup Ghosh, Arpan Kar +1
In the light of the recently observed XENON1T electronic recoil (ER) data, we investigate the possibility of constraining the parameter space of a generic fermionic warm dark matte…
Cosmology of complex scalar dark matter: interplay of self-scattering and annihilation
Avirup Ghosh, Deep Ghosh, Satyanarayan Mukhopadhyay
The cosmology of a standard model (SM) gauge singlet complex scalar dark matter (DM), stabilized by a reflection symmetry, is studied including all renormalizable interactions that…
Revisiting the role of CP-conserving processes in cosmological particle-antiparticle asymmetries
Avirup Ghosh, Deep Ghosh, Satyanarayan Mukhopadhyay
We point out qualitatively different possibilities on the role of CP-conserving processes in generating cosmological particle-antiparticle asymmetries, with illustrative examples f…
